Yes, almost always. A typical 4 kWp system in this latitude generates around 3,400 to 3,800 kWh a year. At current electricity prices that is roughly £900 to £1,100 in saved bills annually, before any export earnings. Payback for most homeowners is between six and eight years, after which you generate free electricity for the remaining lifespan of the panels.

Modern panels generate even in diffuse light, just less of it. Winter months produce around 15 to 25 percent of summer output. Adding a battery means you store the long summer days and draw from them later. With a battery, most family homes hit 80 to 90 percent solar self-sufficiency in summer and 25 to 40 percent in winter.

VAT on residential solar is zero-rated until 2027. The Smart Export Guarantee pays you for every unit you export back to the grid, typically 10 to 15 pence per kWh depending on the tariff. ECO4 grants are available for low-income households and we run those at no cost to you.

No. We use rail-mounted brackets that lift on to existing slates or tiles without penetrating the membrane. Every install includes a roof inspection beforehand and the installation is covered by a twenty-five-year workmanship and weather-tightness guarantee.
